F DAYTON, OHIO, A CORPORATION OF DELAWARE REFBIGEBATING APPARATUS Application'filed November '30, 1929. Serial No. 410,764.

This invention relates to refrigerating apparatus and particularly to the evaporator of said refrigerating apparatus. An object of the invention is to provide means for readily attaching or detaching a front panel to the evaporator of a refrigerating apparatus.

Further objects and advantages of the present invention will be apparent from the fol- 1t lowing description, reference being had to the accompanying drawings wherein a preferred embodiment of one form of the present invention is clearly shown.

In the drawings: Fig. 1 is a side view'of an evaporator to which the invention has been applied;

Fig. 2 is a front view of the evaporator of Fig. 1; i

Fig. 3 is a cross section on lines 3-3 of I Fig. 1; and

Fig. 4 is a cross section on line 4-4 of Fig.

2 with the ice making containers in place.

In attaching a porcelain coated front panel to the evaporator of a refrigerating appara- 2 tus there is considerable dangerofchipping or cracking the porcelain especially i it is desired to makethe panel one that. may be frequently assembled to and dis-assembled from the front of the evaporator. Accordingly this invention provides means whereby such a front panel may be readily attached or removed from the evaporator element without danger of chipping or cracking the porcelain.

In the drawings is disclosed an evaporator 10 such as the flooded float controlled type disclosed in the patent to R. G. Osborn, Serial No. 1,556,708 issued October 18, 1925. ThlS evaporator has let valves 12, which it is desired to conceal uty. The evaporator has for the sake of hen the depending tubes or ducts 13 providing to receive ice a freezing enclosureadapted I making containers or ice trays. Fins 14 may be attached to these tubes or ducts if desired.

VVit-hin this freezingenclosure are preferably two or more shelves 15 and 16. These shelves are referably enclosed except for one open end 1 and are also preferably slightly spaced from one another vertically. A supthe usual inlet valves 11, outporter strip 18 extends from one shelf to the other preferably at either side thereof and is securely attached to each one by a fastening means 19 such as a screw. On the inside of the shelf at the place of this screw is preferably an outwardly extending flange member 20 extending out of the shelf in a horizontal direction to provide means for spacing the front 21 of the ice makin container 22 in order to prevent a very-tig t freezing of the'tray front to the front of the evaporator. Thus the screw 19 provides a unitary securing means for both the" bumper 20 and the supporter strip 18.

At the top and bottom of the strip are preferably outwardly extending flanges 23 spaced in a vertical plane slightly behind the front 17 of the shelves 15 and 16. At the approximate center of the strip is an inwardly turned flange 24 extending into the space between the two shelves 15 and 16. This flange 24 has a screw threaded hole 25 extending therethrough. A similar construction is on the opposite side ofthe twovshelves 15 and 16.

A front panel 26 is then placed on the front of the evaporator and has preferably the contour disclosed in Fig. l with the upper portion 27 bent out to cover the valves 11 and 12. This front panel 26 is preferably porcelain covered to provide a very easil cleaned surface. This very easily cleaner surface however is very easily chipped or cracked and, as it has to be removed for access to the valves 11 and 12, it presents a problem solved by this invention to provide meansfor readily attaching or detaching this front panel without danger of chipping or cracking the This strip has resilient ends 30 bent ened it will gradually clamp the front panel 26 between its slightly resilient ends 80 and the flanges 23 of the supporting strips 18. As the pressure exerted against the panel is very gradual through the slov forward movement of the screws 31 and as the ends 30 gradually straightened slightly there is no danger of chipping or cracking the front of the panel 26 due to the gentleness of the clamping pressure.

Accordingly there has been disclosed means for gradually and gently clamping the front panel 26 to the front of the evaporator in a manner that will not chip or crack the delicate front of the panel.

While the form of embodiment of the invention as herein disclosed constitutes a prcferred form, it is to be understood that other forms might be adopted, all coming Within the scope of the claims which follow.

What is claimed is as follow.

1. A. refrigerating element for refrigerating apparatus comprising in combination a freezing enclosure adapted to receive icemaking containers, at least two shelves in said enclosure spaced from one another, a supporting strip extending from one shelf to the other, a front panel for said element having an opening therein for access to said shelves and a strip across said opening adapted to clamp said iront panel in position.

2. A refrigerating element for refrigerating apparatus comprising in combination a freezing enclosure adapted to receive icemaking containers, at least two shelves in said enclosure spaced from, one another, a supporting strip extending from one shelf to the other, a front panel for said element having an opening therein for access to said shelves and a strip across said opening adapted to clamp said front panel in position and to cover the space between said shelves 3. A refrigerating element for refrigerating apparatus comprising in combination a freezing enclosure adapted to receive icemaking' containers, at least two shelves in said enclosure spaced from one another, a supporting strip extending from one shelf tothe other, a front panel for said element having an opening therein for access to said shelves and a strip across said opening adapted to clamp said front panel in position and to cover the space between said shelves said strip having resilient end portions for making contact with the front of said front panel.

In testimony whereof I hereto afilx my signature.
